retitle 1086272 gromacs: FTBFS with OpenMPI 5 on systems with less than 4 CPUs severity 1086272 important thanks
Hi. Thanks for finding a fix for this so quickly. Nicholas Breen wrote:
Looks like OpenMPI 5 has changed the options to allow oversubscription - but this should only affect running tests on single core/single thread hosts.
Well, just to clarify: I included a build log made in a single-cpu system because sequential logs are usually easier to read and debug, but I also tried on a system with 2 CPUs and it also failed. In fact, the build log contains this: 28: There are not enough slots available in the system to satisfy the 4 28: slots that were requested by the application: So any system with less than 4 CPUs will be also affected. (I understand that you don't want this bug to be RC, but please do not downgrade below important, this is the kind of bug which I usually try to fix in stable (on the teams I am a member of), and for that the RMs require the bug to be >= important). While we are at it: Could you please fix a similar bug in the "elpa" package? (both in trixie/sid, which fails in the same way as this one because of OpenMPI 5, and in bookworm, for which the previous fix in trixie did not reach propose-updates yet). Thanks.
